BURNER-TIP.

PI-ICIPICATION forming part Of Letters Patent NO. 391,379, dated April 17, 188.8.

Application filed November 1,1880. SerialNo. 217,685. (No model.)

To all whom it may concern.-

Be it known that I, \VALTER MARsH JACK- soN, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Burner-Tips; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

My invention relates to an improvement in burner-tips, the object of the same being to provide a burner-tip with a gas-regulating de vice therein, whereby the regulator can be applied to a gas-burner without removing the pillar from the fixture.

With this end in View my invention consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a View in section of an ordinary burner-tip embodying my invention, and Fig. 2 is an enlarged View of the regulator detached.

In the construction represented in Fig. 1, A represents a gastip of the ordinary construction; and B is the regulator, consisting, essentially, of the hollow cylinder A, open at one end and closed at the other, the cylinder B, also open at one end and closed at the other, and the base or disk O, which is preferably flat and provided at its periphery with an upwardlyturned flange within which the open end of cylinder B snugly fits, forminga gastightjoint.

The cylinder A, while it can be made of thin metal covered with paper, is preferably constructed wholly out of smooth hard paper,and is provided with an opening, a, formed at or approximately at the center of said closed end. This openinga is of a size sufficient to pass the desired or predetermined quantity of gas to be consumed under the lowest pressure established asastandard of comniencementof regulation'say,four-tenths of an inch water-pressure. Under such conditions the hole a would be about one-sixteenth of an inch in diameter for five feet of gas of about six hundred specific gravity-large holes for more gas and smaller holes for less gas.

The cylinder 13, which, as before stated, is closed at one end and open at the other, is also constructed of paper or of metal lined with paper, and is provided at apoint near its upper two holes the aggregate capacities of which,

will be greater,ihan the hole a; or the holes 0 may be made in the side of cylinder B nearits top.

The base or disk 0 is preferably flat and provided at its outer edge with an upwardlyturned flange, d. This disk is also provided with a centrally-located opening of a size suffieient to pass any quantity of gas desired under the low standard of pressure.

The three parts above described constitute the regulator, and are assembled as follows: The cylinder A is placed Within the cylinder B and is locked to diskO by forcing the open end of cylinder 13 down within the flange d, forming a gastight joint. The cylinder A is shorter than cylinder B and of less diameter, and when the cylinder A,whieh is free to rise and fall, is resting on the disk 0 the upper end thereof reaches the bottom or lower edge of the holes when in the side of cylinderB and falls short of the holes a when located in the top.

The device as thus constructed is placed Within a common burner-tip, fitting the tip gas-tight at thepoint ofcontact with the flange (Z. The tip is now ready to be inserted in the pillar. As the gas rushes into the pillar, it cannot pass by the flange (Z, but is forced to enter through the hole in disk 0, where it comes in contact with cylinder A. The gas then passes through the hole in the closed head thereof and escapes through the holes in the side or top of cylinder B. If the gas-pressure be, say, four-tenths of an inch, just five cubic feet will pass per hour. If the pressure rises above this, it exerts its force against the cylinder A,which is extremely light and lifts same until the upper end of it rises above the lower edges of the side holes or near to holes a in the top, and consequently diminishes the quantity of gas escaping from the cylinder B by decreasing the size of the escape-openings in said cylinder. This rise and fall of the cylinder A regulates the flow of gas with great precision.

It will be seen that, inasmuch as the area'of cylinder A is increased or diminished by the size of its delivering-hole, the low point of pressure at which it commences to regulate would constantly change unless some provision were made by which the dynamic condition would be unchanged. For this purpose I make the cylinder A so that I can increase or diminish its Weight at will by placing inside any suitable weight, a*. The more gas required to be consumed the lighter the cylinder or disk A and the less gas the heavier.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

WALTER MARSH JACKSON.
